Even after prominent symptoms such as headaches and dizziness subside, the brain still needs time to fully recover from a concussion.

This article reviews the importance of spending an appropriate amount of time recovering from a concussion and the risks possible with inadequate recovery time.

The Importance of Brain Rest

Brain rest has been shown to reduce recovery times in concussion patients. Depending on personal and professional commitments, it can be difficult to take the time necessary to recover. However, getting brain rest (limiting all non-critical cognitive activity) following a concussion, then resuming daily activities slowly, will take less time for patients in the long run than charging through their typical day-to-day activities without taking adequate time off to heal.

See Brain Rest and Concussion Recovery

One recent study that examined the impact of cognitive rest on concussion recovery times saw patients who limited their cognitive activity make full recoveries from their concussions (including all lingering post-concussive symptoms) in half as much time as patients who did not change their behavior.1

Cognitive Importance of Recovery Time

Concussion can affect many areas of cognition, including attention and concentration, processing speed and efficiency, long-term memory and learning, working memory, and verbal fluency.

Concussion patients who cannot or will not engage in brain rest after their injuries are at risk of prolonging or exacerbating their cognitive symptoms.

Physical Importance of Recovery Time

After a concussive event, the brain experiences metabolic changes2 that make it more vulnerable to cell death upon second injury—even one of less intensity.3

Without adequate recovery time, the brain’s natural regulatory systems cannot effectively protect against head injury. This makes concussion patients vulnerable to a number of post-concussive risk, including brain herniation and death.

Emotional Importance of Recovery Time

Anxiety, mood swings, depression, irritability and outbursts, and other psychological and psychiatric symptoms may worsen from a concussion and persist without adequate rest. Concussion recovery can be frustrating and stressful; patients who get adequate brain rest and physical rest may be less stressed and better able to cope during recovery.4
